Hi @probablyup

Unfortunately, this would not work. The Netlify calls plugins before the deploy, and in fact that's the purpose of testing the local built site - to ensure that it won't be deployed if there are failing tests. See https://docs.netlify.com/configure-builds/build-plugins/create-plugins/#plug-in-to-build-events

I am waiting for Netlify to implement onDeployed hook that would be executed after a successful deploy, then we could just run the tests against the DEPLOY url.

@bahmutov yeah that makes sense, I ended up setting things up using github actions to achieve the same effect:

- name: Waiting for 200 from Netlify Deploy
  uses: probablyup/[email protected]
  id: waitForDeployment
  with:
    site_id: "[redacted]"
  env:
    NETLIFY_TOKEN: ${{ secrets.NETLIFY_TOKEN }}

- name: Run Cypress
  uses: cypress-io/github-action@v2
  with:
    record: true
    config: baseUrl=${{ steps.waitForDeployment.outputs.url }}
  env:
    # pass the Dashboard record key as an environment variable
    CYPRESS_RECORD_KEY: ${{ secrets.CYPRESS_RECORD_KEY }}
    # pass GitHub token to allow accurately detecting a build vs a re-run build
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
